Is there one lens solution to cover 12-100 equivlent?

I have Panasonic GX7 with kit 14-42 lens. But for traveling, I would like to have one lens to cover 12mm-approx 100mm focal length. I understand that I can buy 45-150 lens but sometimes it is not convenient to change lens when you are in a hurry, or in a very dusty conditions.

I was thinking of either buy Panasonic 12-35 and add tele converter to reach further or buy Panasonic 14-140 and add wide converter lens.
Is this feasible option in image quality and does this make sense to you? Or my real option is to get two lens to cover these focal length?

Depending on the travel destination, but I would most likely take the 12-35 2.8 instead of something like a 14-140. The 2.8 aperture will offer me more lattitude during the day through the night, I prefer this over the longer range. YMMV.

Me, too, although I'd like it to be a little longer. Maybe 12-200mm?

My current travel solution is the 14-140mm and the 9-18mm. I also travel with two bodies, so on a day where I expect to need the full range I can choose to carry both lenses ready to shoot. Or not, depending on how much weight I feel like lugging.

In Africa a couple of years ago I carried the 14-140mm and the 100-300mm, both on bodies. But we were mostly in game drive vehicles so I had my bag on the seat next to me, could swap easily, and didn't have to carry the weight.

If we're limiting ourselves to a single Panasonic micro four-thirds body, the 14-140 makes the most sense. And the 14-140 with 100-300 makes a fantastic travel duo if we think we're really going to need strong telephoto capability.

But if if one is willing to consider a smaller sensor, wants maximum flexibility and simply doesn't want to change lenses, then one can't do much better than the Olympus Stylus 1. 28-300mm equivalent at a constant aperture of f/2.8. High-quality EVF and the entire kit is jacket pocketable when powered down. $699.

The problem with tele converters with the current m43 long lenses is that they're too slow. You put a 1.4x on a 5.6 lens, and you're at f/8; with a 2x you're at f/11. That's too dark for autofocus to work reliably. With a 2.8 lens you would be at f/4 and f/5.6, which is fine for AF.

This is is one place the Nikon 1 system has an advantage: AF, AE and VR using the FT1 adaptor and any AF-S lens, and a 2.7 crop. So the Nikon 70-300/3.5-5.6 gains the FOV of a 189-810/3.5-5.6 with full automation (although only only AF spot).

I shoot Olympus but I love my 14-150mm for travel. If I could take only one lens, it would be that. It also gets used for events which I have to shoot as part of my job. To me if you need wider than 14mm, shoot multiple shots and stick them together later.
